It is very simple to install and use solution and also very cost-effective as it is included in all vSphere Editions higher than vSphere Essential Plus.
The installation is straight forward
- Download the installation package (ISO)
- Mount ISO
- Deploy OVF (Virtual Appliance in Open Virtual Format)
- Configure Virtual Appliance to register into vCenter
- vSphere_Replication_OVF10.ovf - Use this file to install all VR components, including the vSphere Replication Management Server and a vSphere Replication Server.
- vSphere_Replication_AddOn_OVF10.ovf - Use this file to install an optional additional vSphere Replication Server.
- vSphere Replication supports RPO 5 min and higher, therefore it is an asynchronous replication and you cannot use it if you have strict RPO Zero requirement. However, do your business really require RPO Zero? Do not hesitate to ask and challenge somebody responsible for Business Impact Analysis and costs associated with it. Do not simply assume you cannot lose any data. There should always be a risk management exercise.
- vSphere Replication is a one-to-one VM mapping and not one-to-many. While you can replicate to multiple vCenters (target sites), only one VM can be replicated to one target vCenter. Here are further details and supported topologies.
- vSphere Replication supports up to 24 recover points. These 24 recover points can have retention for up to 24 days or you can configure up to 24 snapshots per 1 day. So you can spread these 24 recover points within these guide rails based on your specific business requirements.
